High definition by Ricoh original MEMS technology

By using MEMS technology, Ricoh's unique design means the RICOH TH5241 is a compact printhead with 320 x 4 rows of 1,280 nozzles*. In addition, high-definition printing of up to 1,200 dpi can be achieved by jetting fine droplets.
* There are two sets of 600npi with a staggered arrangement of 300npi nozzles per row.

RIOCH TH5241 supports multi-drop technology that controls drop volume by merging several droplets in flight before reaching a media surface. It enables grayscale expressions.
